12.5. How to install electrical wiring: Installation of distribution boards

Starting the installation of electrical wiring in a house is a task that requires a lot of attention and technical knowledge. It is essential to understand that safety must be the priority throughout the process. The first step in installing electrical wiring is the installation of distribution boards, which are essential for the proper functioning of the electrical system.

Distribution Boards

Distribution boards, also known as electrical panels, are the backbone of any electrical system. They are responsible for distributing the electrical energy that arrives at the house to the various electrical circuits present. Each circuit is responsible for feeding a specific set of equipment or light points.

Choosing the Distribution Board

The choice of distribution board should be based on the amount of circuits that the house will have. Each circuit requires a circuit breaker, which is a safety device that automatically shuts off the circuit in the event of an overload or short circuit. Therefore, the number of breakers will determine the size of the switchboard.

Distribution Board Installation

The installation of the distribution board must be done in an easily accessible place that is protected from adverse conditions, such as humidity and excessive heat. The frame must be fixed to the wall using screws and wall plugs suitable to support its weight. It is important to ensure the frame is level and secure before proceeding with the installation of circuit breakers and wiring.

Installation of Circuit Breakers

The circuit breakers are installed in the distribution board. Each breaker is connected to a specific circuit. The installation of circuit breakers must be carried out in accordance with the manufacturer's specifications and the applicable technical standards. It is important to ensure that each breaker is properly labeled to facilitate maintenance and troubleshooting in the future.

Wiring Installation

After installing the breakers, it's time to install the wiring. Wiring must be done using quality electrical cables and in accordance with technical standards. Each cable must be connected to the corresponding breaker on the distribution board and then lead to the light point or equipment that will be powered. It is important to ensure that the wiring is properly protected and insulated to prevent accidents.

Testing and Verification

Once the wiring is installed, it is necessary to perform a test to verify that everything is working correctly. This test should include checking the voltage at each light point and fixture, checking the operation of circuit breakers, and checking the integrity of the wiring. Any problems detected must be corrected before putting the system into operation.

In summary, the installation of electrical wiring and distribution boards is a complex task that requires technical knowledge and attention to detail. Safety must always be the priority throughout the process. If you do not feel comfortable or confident performing this task, we highly recommend hiring a qualified professional to do it.
